We discuss some properties of Cohen and random reals. We prove a general combinatrial fact about them which in partìcular implies that they are large, they contain arbitrary large arithmetical or geometrical progressions, satisfy the Hindman's conclusion and so on. We also show that they are wild in the sense of minimal theory. We also investigate how badly approximable are they by algebraic numbers.

This is a work in progress with Will Brian.
